Watching your daughter's hair thin out or fall out is understandably upsetting, but the symptoms you describe are not classic of hypothyroidism- too little thyroid hormone produced. What your daughter may have is a scalp condition called Telogen effluvium, a sudden thinning of hair throughout the scalp. The condition is not serious, and the hair loss is not total or permanent. Nor does it come out in clumps, like another type of hair loss called alopecia. Telogen effluvium can occur following a viral illness, high fever, and in some cases can be related to some hormonal conditions. During the time of the illness, hairs that were in their growth phase can change into the resting phase of hair growth. Weeks later, the hair begins to shed and this can last up to six weeks. It takes three to six months to re-enter the growth phase-so be patient. Your pediatrician should take a look to see if any further tests should be done or if your daughter should be referred to a dermatologist.

The “stomache bug” or virus that caused your son’s diarrhea is long gone- but the effect it had on his intestines is not. Diarrhea washes away some important digestive enzymes that are necessary for fluids to be absorbed back into the body. The loss of lactase for example results in a lactose intolerance.  Postinfectious diarrhea can take several weeks for the lining of the intestine to return to normal. At this point avoiding milk and sugary juices, and eating a normal diet is in order, including fats which help slow down the intestines and proteins which help the lining heal. You should see improvement over a 1-2 week period. If the diarrhea persists after a week or two, have your pediatrician reevaluate your son or refer him to a pediatric gastroenterologist.

Its not just diarrhea its vomiting. Just when we think the bug is finally gone its starts again. My oldest threw up again last night after not getting sick for a couple of weeks.

He had been fine.

We have kept him on a dairy free low fat diet but if we steer away from that diet it aggrivates things. After 3 months he is also starving and getting really sick of the diet as we all are.

We have taken them to the ped over and over, but he doesn't seem concerned as they haven't lost weight.

Its still going around the school as entire tables of kids in my youngest sons class have been absent. The only thing the school does is they now ask why they are absent, so i think they are tracking who all has this bug.

I just want it gone!

Unfortunately there is no scientific evidence that diet has an effect on children with Asperger's Syndrome. This includes diets that are gluten free, casein free, milk and dairy free, the Feingold diet, or any others. Muchanectodal evidence is found on line but is not supported by any research studies. Please discuss this topic with your child's pediatrician or neurologist. They can give you more information.
